中文摘要:
      从理论上研究了三维狄拉克半金属(3D DSM) 与石墨烯结合的红外波段的古斯—汉欣(GH) 效应, 并与石英玻璃的GH效应进行了对比.结果表明: 覆盖石墨烯加剧了反射光相位的变化, 明显增强了GH位移, 改变了GH位移的正负.p偏振的光以布儒斯特角入射时,覆盖有石墨烯的 3D DSM 的GH位移出现正向峰.3D DSM 的GH位移对于平板厚度比石英玻璃敏感,随平板厚度变化时出现震荡峰.在金属区域和高损耗电介质区域, GH位移接近零; 在无损耗电介质区域,GH位移随波长变化呈现震荡特性.
英文摘要:
      Goos-H?nchen (GH) effect of graphene coated three-dimensional Dirac semimetal in infrared range was investigated theoretically and compared with that of silica glass. The results indicated that variation of the reflection phase and GH shift is enhanced and sign of GH shift is changed through coating graphene. When the p polarized light is incident at the Brewster angle, GH shift of graphene coated 3D DSM has positive peak. GH shift of 3D DSM is more sensitive about the thickness of slab than that of silica glass and shows oscillating peaks with changing the thickness of slab. In the metallic region and the dielectric region with high loss, GH shift is close to zero; in the dielectric region without loss, GH shift is oscillating with varying wavelength.
